The switching valve device A and the foot nozzle 13 communicate with each other through a foot pipe 17, and the switching valve device A and the back nozzle communicate with each other through a back pipe 18 so that the switching valve device A and the shoulder nozzle communicate with each other. The nozzle 6 is communicated with the shoulder pipe 21. Further, air is supplied to the foot nozzle 13 and the back nozzle from the air suction port 19 through the air pipe 20.

FIG. 1 shows an embodiment of the switching valve device A. An inflow port 2 is provided in the lower portion of the valve body 1, and a foot outlet 4 and a back outlet 5 are provided on both left and right sides of the valve body 1, and a shoulder outlet is provided above the back outlet 5. A discharge port 7 is provided. The foot outlet 4 and the back outlet 5 are provided so that the foot outlet 4 is located above. A foot pipe 17 is connected to the foot outlet 4, a back pipe 18 is connected to the back outlet 5, and a shoulder pipe 21 is connected to the shoulder outlet 7. is there. A cylindrical sluice valve 8 is rotatably installed in the lower portion of the valve body 1, and the sluice valve 8 has an opening 8a that can communicate with the foot outlet 4 and an opening that can communicate with the back outlet 5. 8b is provided. A ball valve 9 is rotatably provided in the upper portion of the valve body 1. An inverted L-shaped flow passage 9a is provided in the ball valve 9 so as to open and close between the inflow port 2 and the shoulder discharge port 7. The ball valve 9 and the sluice valve 8 are connected by a spring pin 22. Here, 23 is a ball seat that seals the ball valve 9, 24 is a ball seat presser that presses the ball seat 23 against the ball valve 9, 25 is a ball valve unit main body that fixes members around the ball valve 9, and 26 is a ball valve. This is a C ring that prevents the unit body 25 from slipping out. The upper portion of the valve body 1 is attached to the flange 16 with fixing nuts 27 and 28. An operating knob 10 exposed on the flange 16 is rotatably mounted on the upper end of the valve body 1, and a valve shaft 11 provided integrally with the operating knob 10 is connected to the ball valve 9. Reference numeral 29 is a decorative cover that hides the fixing nut 27, and the locking foot 29c of the decorative cover 29 is locked and attached to the inner circumference of the upper end of the valve body 1.

In the switching valve device A configured as described above, by rotating the operation knob 10, the ball valve 9 and the sluice valve 8 rotate, and the foot outlet 4, the back outlet 5, and the shoulder outlet 5 are rotated. The discharge port 7 is opened and closed. FIG. 2 illustrates the operation in detail. This is a structure in which the back side, the foot side, and the shoulder side are switched by rotating 180 degrees. 2 (a) shows a state in which water is being discharged from the foot outlet 4, and when the operating knob 10 is turned counterclockwise from this state, water is gradually discharged from the back outlet 5 and FIG. As shown in (), water is discharged from both the foot outlet 4 and the back outlet 5. When the operation knob 10 is further turned counterclockwise, the foot side outlet 4 is gradually closed, and as shown in FIG. 2C, only the back side is in a state of discharging water. When the operating knob 10 is further turned to the left from that state, the shoulder outlet 7 is gradually opened and the shoulder outlet 7 is fully opened. At this time, the flow rate can be adjusted by rotationally adjusting the operating knob 10 between the back and the shoulder. The operation knob 10 is provided with a stopper so that it can be rotated by 180 °. If maintenance becomes necessary, the operation knob 10 and the decorative cover 29 are removed, the C ring 26 is removed, and the valve shaft 11 is pulled, whereby the ball valve unit body 25, the ball valve 9 and the sluice valve 8 are removed. All can be pulled out and maintained.

FIG. 3 shows another embodiment of the switching valve device A. In the case of this embodiment, the foot outlet 4 and the back outlet 5 are provided at the same level. The other structure is the same as that of the embodiment shown in FIG. FIG. 4 shows the structure of FIG. 3 which is switched by rotating the operation knob 10 by 120 °. 4 (a) shows a state in which only the foot outlet 4 is open, and FIG. 4 (b) shows a state in which both the foot outlet 4 and the back outlet 5 are open, and FIG. Shows a state in which only the back discharge port 5 is open, and FIG. 4 (d) shows a state in which only the shoulder discharge port 7 is open.

By the way, in order to give a bather a sufficient massage feeling in this type of bathtub, it is necessary to secure a sufficient flow rate to the foot nozzle 13 and the back nozzle, and for that purpose It is necessary to make the flow path diameters of the outlet 4 and the back discharge port 5 sufficiently large, and also to make the sizes of the openings 8a and 8b of the sluice valve 8 sufficiently large. However, when the foot outlet 4 and the back outlet 5 are provided at the same level as in the embodiment of FIG. 3, the diameter of the sluice valve 8 becomes large when the flow passage diameter is set sufficiently large as described above. There is a problem that the valve body 1 becomes larger, the diameter of the valve body 1 becomes larger, the mounting position of the bathtub 3 on the flange 16 is limited, and the bathtub 3 cannot be mounted depending on the type of the bathtub 3. Therefore, if the positions of the foot outlet 4 and the back outlet 5 are vertically stepped as in the embodiment shown in FIG. 1, the openings 8 and 8b of the sluice valve 8 can also be vertically stepped. The discharge port 4, the back discharge port 5 and the sluice valve 8 can have sufficient openings, and the valve body 1 can be made compact without increasing its diameter. When comparing FIG. 2 (a) and FIG. 4 (a), the openings 8a, 8b of the sluice valve 8 require a certain area or more in order to secure the flow rate. In the case of having a structure, the diameter of the gate valve 8 becomes large because two openings 8a and 8b are provided on the same surface as shown in FIG. Therefore, when the openings 8a and 8b of the sluice valve 8 are vertically displaced as shown in FIG. 1, the diameter of the sluice valve 8 does not have to be increased because the openings 8a and 8b are not on the same plane. As a result, the valve body 1 can be made compact without increasing its diameter.

Further, in FIG. 5, the operation knob 10 is switched by rotating it by 180 °, but it is discharged from the shoulder discharge port 7 at 0 ° and 180 °. FIG. 5A shows a state in which only the foot outlet 4 is ejected, FIG. 5B shows a state in which only the back outlet 5 is ejected, and FIG. 5C shows a foot outlet. 4 (d) and 5 (e), the discharge is being performed from only the shoulder discharge port 7.

6 and 7 are switched by rotating the operation knob 10 by 360 °, it is possible to discharge from all of the foot outlet 4, the back outlet 5, and the shoulder outlet 7. It is a scam. 6 (a) shows a state in which only the foot outlet 4 is discharged, FIG. 6 (b) shows a state in which only the back outlet 5 is discharged, and FIG. 6 (c) shows a foot outlet 4 and a back portion. 6 (d) and 6 (e) show a state of discharging from only the shoulder discharge port 7 and FIG. 6 (f) shows a state of discharging from the foot discharge port 4 and the back discharge port 5 respectively. And the discharge ports 7 for shoulders are all discharged.

In FIG. 7, since the foot outlet 4 and the back outlet 5 are connected at positions deviated from the center of the valve, the operation knob 10 is switched by rotating it by 360 °, but it is adjusted at a large angle. You can do it. FIG. 7 (a) shows a state of discharging only from the foot outlet 4, FIG. 7 (b) shows a state of discharging only from the back outlet 5, and FIG. 7 (c) shows a state of discharging from the foot outlet 4 and the back. 7D shows a state in which the ink is discharged from both of the discharge ports 5 for shoulders, and FIG.
